ns-level time transfer over a microwave link using the PTP-WR protocol

Pierre-André Farine, Cyril Botteron, Jean-Pierre Aubry, Mathieu Paul Joseph Carlos Rico

Today it is possible to achieve sub-ns level time synchronization on a wireline network while only us-level synchronization can be achieved on a wireless (microwave) link. In this paper we will, first, study the performances of different time synchronizati ...

Diversity Gain Influenced by Polarization and Spatial Diversity Techniques in Ultrawideband

Anja Skrivervik, Mohsen Koohestani

This paper presents an experimental investigation of diversity gain influenced by polarization and spatial diversity techniques in ultrawideband (UWB) radio technology. To this aim, two different coplanar-fed UWB diversity antennas having the same size and ...

Efficient MAC in cognitive radio systems: A game-theoretic approach

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj

In this paper, we study the problem of efficient medium access control (MAC) among cognitive radio devices that are equipped with multiple radios and thus are capable of transmitting simultaneously at different frequencies (channels). We assume that radios ...

A simple & [and] accessible front-end satellite receiver for communications and e-learning in emerging countries

Olivier Videme Bossou

For the universities of the emergent countries, and those of Cameroon in particular, the fight to reach a durable development requires to know the needed scientific and technical information for their development, how to get it and to spread it out among p ...

A Joint PHY/MAC Architecture for Low-Radiated Power TH-UWB Wireless Ad-Hoc Networks

Jean-Yves Le Boudec, Ruben Merz, Jörg Widmer

Due to environmental concerns and strict constraints on interference imposed on other networks, the radiated power of emerging pervasive wireless networks needs to be strictly limited, yet without sacrificing acceptable data rates. Pulsed Time-Hopping Ultr ...
